i want a d15b7 boosted because i want to prove the haters wrong :thumb: i was thinkin vitara pistons, eagle rods, eagle crank if possible, oem honda bearings, full skunk 2 valvetrain skunk 2 cam, ported polished head, skunk 2 intake mani/throttle body, tuned with hondata s300 will this setup be able to hold 250whp or maybe more :hehe: i know some of you think a boosted D is a waste but its what a want so please no negative comments thanks :thumb:

unfortunatley, there are no 'cheap' rods for the d15's.
vitara builds do work well with d16's and the jdm d15b vtec (because it uses d16 rods).
here is a 600+ hp vitara build:

Boosted D = proven :thumb:
Boosted D15b7 = :cry:

The aftermarket is not there for the D15b7. I may not be up to date on what's out there, but I didn't think those internals were available for the D15b7 :?

Not saying it can't be done though... everyone thinks you need to have vtec to bother building a turbo D setup. Not at all! There used to be a boosted D16y7 running around NE OH making almost 400whp. It was a stock looking sedan too 8) :zzz: :twisted:

It's more that the aftermarket is there for the D series which have vtec.

it will work but not up to 250 hp. youll end up snaping a rod or somthing. even if the motor was fresh with all oem internals with boost your not going to hit 250hp.

pretty sure the stock rods in those start to bend once you get to the 200whp range...

well i might just boost it on stock internals until it blows up and then switch to a d16y8 block :?

why don't you just build a motor? your just gonna waste time swaping when it blows. by a block and head. get the shit you wanna put in and take to a shop and have em do the head up and the block and the you will have a nice motor. find a turbo and a ecu tune and you will have a nice motor tha will last for a while. :thumb:

y8/y7 cranks and oil pumps suck ass (not in a good way) and eat rod bearings.
you'll be better off building your z6 with teh vitaras.
i'm only pointing this out because the word 'reliable' was used in the title of this post

well i want to i just say ill boost it until it blows because running d15s go really cheap around here. anyway it seems like i would be better going with a d16z6 or y8 because of the aftermarket support

d15b7 block + d15b crank + d16z6 rods could work I heard somewhere.
Not really sure

Skunk2 also doesnt make cams for non vtec motors.

i just built my z6 with vitaras and FJ custom length I-Beam rods, i would look at FJdistributors...they have custom rods for both the d16 and d15, handle up to 500+whp

i'm going to be boosting up to what my "stage 1" clutch can handle ... just get a good tune and don't push more than ~220whp on stock d rods. boost spike/detonation of any sort and your done
